Links XPS for Nortec GSTC/ SETC B+ | 1

Overview

The GS/SE Links XPS Option allows for the integration of a Nortec GSTC/ SETC Series humidifier

within a BACnet, Johnson N2 or LonWorks network. This option features a gateway that has the

capability of converting information from the host Modbus protocol to a specified secondary

protocol.

The following protocol options are available, and must be specified at time of order:

Multi-Unit Systems (“Master/Slave”)

Up to 8 humidifiers can be chained and monitored through a single Links XPS package. In this

configuration, the unit with the Links XPS package is designated the “Master Unit”, while the

remaining 7 humidifiers are configured as “Slaves”. The master unit is connected to the

Building Management Systems (BMS). Each unit is separately addressed, it is possible to

monitor and control each unit individually.

Different networking configurations may be achieved depending on the type of network being

used. One networking example could have a Gateway installed inside the lead unit, which could

then be daisy-chained to successive units. In turn, the lead unit would connect to a Building

Management System (BMS) network via a shielded, twisted-pair connection. Please see wiring

section for additional detail. A second example could have a series of units directly connected

to an Ethernet network. This is only possible for BACnet communication and is essentially

referred to as a BACnet/IP configuration.

Wiring the Links XPS Module

Most of the wiring connections for the new Links XPS module will have already been finished at

the factory, however, there are a few connections that will need to be made to connect the unit

the Nortec GSTC/ SETC series humidifier. Refer the LINKS XPS wiring diagram included in the

package for details.

Module Power Connections: There will be a wire harness provided that will consist of a red and

blue wire. Both red and blue wires are terminated with a ring terminal.

Figure 3: Wires from Links XPS Bracket

a. The ring terminal of the red wire is to be connected to the power terminal on the 24V

side of the transformer located at the bottom, left of the electrical compartment.

b. The ring terminal of the blue wire is to be connected to the ground terminal on the 24V

side of the transformer.

Links XPS for Nortec GSTC/ SETC B+ | 5

Humidifier Communication Connection: On the Links XPS assembly there will be a CAT5 cable

with RJ45 connector.

This connector is to be plugged into the jack on the bottom right side of the humidifier main PCB

processor board (Keypad chip).

Figure 4: Backside View of Humidifier PCB Board

6 | Links XPS Nortec GSTC/ SETC B+

Configuring the Humidifiers

The PCB processor board will need to be configured to work with the Links XPS modules. Since

Links XPS can connect to a maximum of 8 units, it will be necessary to set the unit address for

each humidifier. The lead unit can be determined by the presence of the Links XPS module. The

slave humidifiers can be given a unit address according to the number the unit will have on the

networked chain.

Links XPS can be used for control, monitoring, or both. To set the control mode on the

humidifier, on the humidifier refer to the procedure in the Nortec GSTC/ SETC Installation and

Operation Manual to enter the controls menu.

If you would like to control the humidifier directly by signal writing values over the Links XPS

package set the Signal Source to digital. The humidifier will now look for values to be written to

the humidifier.

If you would like to use an analog control signal (from a wall humidistat or building automation

system) leave the Signal Source to Analog and then set REG mode, MOD mode and CNT type to

match the type of controls being used. Ensure that controls are physically wired to terminals 3

and 4 on the low voltage terminal strip.

To set the humidifier to recognize the Links XPS package:

1. On the humidifier keypad, Press the Menu button on the keypad and enter the password

0335.

2. Select Control Settings

3. Select Modbus Parameters.

4. Set the communication parity to “None1”.

5. Set the appropriate Modbus address according to the unit ordering

6. Place the appropriate Unit Identifier label on each humidifier. These labels should be placed

on the unit where the electrical control punch-outs are located at the top of the humidifier.

7. Connect the slave humidifiers (if applicable) to the Links Module. A twisted pair cable should

be used so that the Net (+) terminal on the Links module should connect to the Net (+)

terminal on the slave unit (NHTC). The Net (–) terminal on the module should be connected

to the Net (–) terminal on the slave unit. Refer to the Links XPS wiring diagram for more

information.

8. Ensure shield wiring matches the following pattern if distances between humidifiers is

significant(2200 ft):

Figure 5: Multiple Slave Humidifiers

Wiring

BACnet MS/TP, Johnson N2, and LonWorks

Links XPS is pre-installed and factory wired, except for the Nortec SETC-050 which is provided in

its own separate enclosure. Connections must be made between the master humidifier and the

Building Management System (BMS), and the master humidifier and any slaves that may be

present.

Up to 8 units (1 master, 7 slaves) may be connected to a BMS through a single gateway in the

master unit. The units are daisy chained via the Links XPS terminal strip. The wire shield

should only be connected at one end per pair of units when “daisy chaining”. Older A and B

style units use a different connection method, please refer to revision C of this manual.

Table 2 refers to the recommended wire types and maximum recommended lengths from the

Links XPS module to the front-end of the Building Management System. Since communication

between the humidifiers and Links XPS occurs via an EIA-485 signal type, Condair recommends

using an 18-24 AWG shielded, 120  twisted pair wire between the lead humidifier and each of

the slave humidifiers. Total cable length runs between the Links XPS module and the furthest

slave humidifier should not exceed 2,000 feet. Signal boosters or repeaters may be necessary

for longer wire runs or where electrical noise interference is prevalent.

A standard CAT-5E cable with an RJ-45 (Ethernet) jack is to be connected to the Ethernet port

on the Links XPS module. Refer to wiring diagrams in this manual.

Cable Shielding

The cable’s shield should be connected to the shield terminal at the BMS system only, and not

the Links XPS module.

As well the cable shield should be connected at the lead unit only and not at subsequent units.

For long chains the shield would appear as:

Unit 2 to Master - Shield connected at master only.

Unit 3 to Unit 2 - Shield connected at unit 2 only.

Unit 4 to Unit 3 - Shield connected at unit 3 only.

And so forth.

Gateway Configuration

Protocol configuration is completed at the factory, prior to final testing. If configuration

information was supplied at the time of order, the units will be configured for plug-and-play

installation with no further configuration required. If this information was unavailable, it will be

necessary to configure the address parameters.

 BACnet IP systems will require a static IP address to communicate on the network, and may

require a device instance and MAC address

 BACnet MS/TP and Johnson N2 systems require both a device instance, MAC address and

a baud rate to be set.

 LonWorks systems automatically detect network address parameters and do not require

configuration.

Changing Unit Device Instance and BACnet MAC Address

The initial step is to determine if both BACnet Device Instance and MAC address can be the

same value. If not, skip to Part B. If yes, continue with Part A using solely the small dipswitches.

Part A: Device Instance and MAC address same value

The device instance and BACnet MAC address can be easily changed to the same value using

the dip switches (SW3 Bank 1 through 8) highlighted on figure 8. Notice these are the smaller

dipswitches, not the larger ones.

Figure 6: Dipswitches for BACnet Address Changes

Links XPS for Nortec GSTC/ SETC B+ | 11

These switches allow you to set a binary value for the device instance between 1 and 127

inclusive. To set the device instance to value outside of this range, skip to PART B. The

methodology for converting numbers to binary is presented in the example below. In this

example, a value of 78 is converted to binary and set as the device instance:

Changing Baud Rate (BACnet MSTP, Johnson N2, LonWorks)

The baud rate for communications must be changed through dipswitches (SW4 Bank, 1 through

4). Refer to figure 7 for location of the dipswitches.

By adjusting the settings according to the table 5, the baud rate can be changed. The Baud rate

must be set to exactly the same baud rate as your Building Management System.

Communication performance varies with building automation system manufacturer and some

experimentation with other baud rates may be required to obtain the best performance.

Part B: Device Instance and MAC address different values

First, ensure the addressing dipswitches (mentioned in Part A) for Bank SW3 are all set to OFF

or are set to 128 or higher. Also ensure your Baud rate dipswitches are properly set (Bank SW4)

see previous chapter for details.

The device instance and BACnet MAC address can now be changed to be different values using

a free software tool. To obtain this program, visit the link below, and then download and install

the latest version of the “Utility Software” (8 MB file called Install.zip).

www.protocessor.com/tech-support/utilities-and-design-documents.php

Figure 8: Retrieval of Protocessor Software Tool

Links XPS for Nortec GSTC/ SETC B+ | 15

Once the free tool has been downloaded to a computer (preferably a laptop), extract and install

it. NOTE: you will require administrative privileges on the computer to perform the installation,

contact your network administrator for assistance. Once completed, use the following steps to

perform the addressing changes:

To change the Device Instance and MAC Address:

1. Connect the computer to the ethernet port of the Links XPS module. (you will need a

Category 5 or better cable (CAT5)

2. Power up the Links XPS module. During the boot process 8 multi-colored LED’s may

illuminate.

3. On the computer navigate to Start > Programs > Fieldserver Utilities > Remote User

Interface.

4. A blue window will launch, running a program named “Remote User Interface”. Any Links

XPS models detected will be listed as “Fieldservers discovered on the network”. If no

modules are detected you will receive the following screen:

This error is most likely due to the network configuration of the computer. By default, the Links

XPS modules ship with an address of 192.168.10.11. If your computer is not already on the

192.168.10.0 domain, you will need to set your computer IP address to a unique address within

this range. You may need to turn off or disable any wireless connections before beginning to

avoid conflicts. For Windows systems, this setting is located in:

Windows XP: Start > Control Panel > Network Connections

Windows Vista, 7: Start > Control Panel > Network and Sharing Center

Windows 8.1: Desktop Start (right click) > Control Panel > Network and Sharing Center
